Abstract

The invention relates to a device for screening pulp, comprising a screen drum (2) provided with holes for the passage of an accepted pulp fraction therethrough; and a blade (10) for a screening device. The device comprises straight blades (10) wiping the surface of the screen drum (2) and extending in parallel with the axis of the screen drum (2). Reject which does not pass through the screen drum (2) is removed through a reject discharge opening (5) at the other end of the screen drum. For transferring the reject from the surface of the screen drum (2) to the reject discharge end, the surface of the blades (10) is on the screen drum side provided with grooves (11) so inclined that the front end of the groove (11) is closer to the pulp input than the backward end of the same groove (11). Thereby each groove (11) in the blades (10) causes the reject to be transferred towards the reject discharge opening (5).
